Answer:[2,8]

Step-by-step explanation:Well since it’s a linear function it’s ends will be the extrema, so plugging the domain restrictions that you are given:

y=-2(1)+10

y=-2+10

y=8

and

y=-2(4)+10

y=-8+10

y=2

so since 2 is lower than 8, its the lower range bound, and since both the 1 and the 4 are included in the domain it will be a closed interval:
